This invention relates to new and useful improvements in foldable lamps.

The invention has for an object the pr vision of a device of the class mentioned which is of simple durable construction, dependable in use and eliicient in action, and which may be man u. ictured and sold at a reasonable cost. The invention proposes a collapsible lamp including a vertical post with a lamp atthe top. and a collapsible lamp shade constructed similar to an umbrella supported on the lam and on the post in a fashion permitting the exchange of the lamp and adjustment to accommodate different sized lamps.

Forfurther comprehension of the invention, and of the objects and advantages there of, reference will be had to the following description and accompanying drawings, and y to the appended claims in which the various 29 novel features at the invention are more particularly set forth.

In the accompanying drawing forming a material. part of this disclosure 1 is a side elevational view ot a device 25 constructed according to this invention.

2 is an enlarged perspective view of the skeleton of the lamp shown in Fig. 1.

Fig. 3 is a fragmentary enlarged detail view of the top portion of 2.

Fig. l is a vertical sectional view of the top pmftion of Fig. 3.

Fig. 5 is a detail view of a portion of Fig. 2.

Fig. 6 is a fragmentary vertical sectional view of Fig. 5.

The reference numeral 10 indicates a base stand provided with a post consisting of a vertical tube 11. A lamp socket 12 is mounted upon the top of the tube 11 and supports a lamp 13. Lamp grips Ll are engaged upon the lamp 13 and are formed of bent wire and connect with a stud cup 15. A tube 16 is slidably mounted upon the cup and has its top edges turned down so as to be in the horizontal. These down turnededges are indicated by reference numeral 17 and are formed with a plurality of radial cuts 18. Set screws 19 threadedly engage in the tube 16 and abut against the stud cup 15 for permitting a longitudinal. adjustment of these parts.

An inner tube 20 is fixed Within the tube 16 and extends above the latter tube and has its top edges turned down into the horizontal. The turned down edges are indicated by rcference numeral 21 and are formed with a pluralityot' radial slots 22 directly above the slots 18. A wire ring 23 is engaged between the horizontal edges 17 and 21.

In each. of the radial slots 18 and 22, one end of a rib 2d engages and is pivotally mounted upon the ring 23. A brace rib 25 pivotally connects intermediate of the ends of each of the ribs 24 and extends inwards towards the post 11. The inner ends of these brace ribs pivotally engage upon a wire rin 26 disposed between the down turned edges of an inner tube 2'? and an outer tube 28. The inner tube is fixed within the outer tube and both of these tubes are slidably mounted upon the post 11. The down turned edges of the inner tube is indicated by reference numeral 29 and is formed with a plurality of radial slots. 30 for receivingthe inner ends of the brace ribs. The down turned edges of the outer tube is indicated by reference numeral 31 and is also formed with a plurality of radial slots 32 aligned with the slots. 30 and for the same purpose.

A collar 33 is slidably mounted upon the lower end of the outer tube and may be fixed in various adjusted stationarypositions by set screws 84 threadedly engaging in the collars and abutting against the outer tube 28. The collar 33 is formed with a vertical slot engageable by a spring pressed catch 36 mounted. in the vertical post 11 and at a posi tion that when engaged. the ribs 24; are held in a spread condition. Cloth material 37 is secured upon the ribs 24.- and constitutes the nml'erial forming the lamp.

The lamp may be collapsed by manual pressing in the catch 36 and then sliding the collar 33 together with the tubular members 27 and 28 downwards so that the brace ribs 2-5 draw the radial ribs 24: down and into closed positions. The lamp 13 may be replaced by forcing the lamp grips 14 off the lamp 13 while the lamp shade is in its collapsed condition. A new lamp may then be engaged in the so'cket12. In the event that the new lamp is of different proportions to inc the one just replaced, the set screws 19 and 214 may be loosened and the parts held by these set screws adjusted for accommodating the new size lamp.

lVhile I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. A lamp of the class described, comprising a vertical postwith a top lamp, a stud cup having depending wire grips engaging the lamp, a plurality of radial ribs pivotally mounted at their inner ends and supported on the stud cup, brace ribs pivotally connected intermediate the ends of said ribs, a collar slidably mounted on the post, the inner ends of the brace ribs being pivotally supported and mounted on the collar, means for holding the collar in a raised position "for holding the radial. ribs spread, and cloth material attached on the radial ribs.

2. A lamp of the class described, comprising a vertical post with a top lamp, a stud cup having depending wire g'ips engaging the lamp, a plurality of radial ribs pivotally mounted at their inner ends and supported on the stud cup, brace ribs pivotally connected intermediate the ends of said ribs. a collar slidably mounted on the post, the inner ends of the brace ribs being pivotally supported and mounted on the collar, means tor holding the collar in a raised position for holding the radial ribs spread, a means for djusting the distance of support oi the radial ribs from the stud cup for accomn'iodating lamps of ditl crent sizes, and cloth material attached on the radial ribs.

5). A lamp of the class described, comprisa vertical post with a top lamp, a stud cup having depending wire grips engaging the lamp, a plurality of radial ribs pivotally mounted at. their inner ends and raipported on the stud cup. brace ribs pivotally connected intermediate the ends of said ribs. a collar slidably mounted on the post, the inner ends ot the brace ribs being pivotally supported and mounted on the collar, means For holding the collar in a raised position for holding); the radial ribs spread, a means for adjusting); the suppi'irt dis ance oi the brace ribs from the collar for acconunoda:'ng lZlllll'JS ot ditl'erent sizes. and cloth niaterial attached on the radial ribs.

In a lamp, a vertical post with a trip lamp, a stud cup having depending wire grips engaging the lamp, a plurality of radial ribs pivotally mounted at their inner ends and supported on the stud cup. brace ribs pivotally connected intermediate the ends of on the stud cup. brace ribs pivotally connected intermediate the ends of said ribs, a collar slidably mounted on the post, the inner ends of the brace ribs being pivotally supported and mounted on the collar. a spring pressed catch on the post for holding the collar in a raised position for holding the radial ribs spread, and cloth material attached on the radial ribs.

In testimony whereof I have atlixcd my signature.
